Description

Technical Field

[0001] This utility model relates to a tobacco transplanting and positioning device, belonging to the field of transplanting and positioning technology. Background Technology

[0002] Before transplanting flue-cured tobacco seedlings, fixed-point markings need to be made on the ridges at fixed intervals. Traditionally, this relies on manual measurement using lines or rulers. This method suffers from high labor intensity, low efficiency, and poor spacing consistency. Existing literature (CN216163342U) discloses a handheld transplanting distance measuring device, which includes a distance measuring ring, a support, and at least one plumb bob. At least one distance measuring tooth is fixedly installed on the outer ring of the distance measuring ring. A rotating shaft is fixedly connected to one end of the support, and the shaft is rotatably connected to the distance measuring ring. Pushing the support rotates the distance measuring ring. Each plumb bob is fixed to the end of the rotating shaft via a connecting rope. Ground marking is achieved by rolling the distance measuring ring with the distance measuring teeth. However, in practice, the distance measuring ring lacks lateral restraint when moving on curved ridges, easily slipping and deviating from a straight line, leading to misaligned marking points. Furthermore, the distance measuring teeth roll directly on the mulched ridges, easily tearing the mulch film. Utility Model Content

[0003] Based on the above, this utility model provides a tobacco transplanting positioning device to overcome the shortcomings of the prior art.

[0004] The technical solution of this utility model is: a tobacco transplanting and positioning device, comprising:

[0005] Push frame;

[0006] The traveling wheels are rotatably mounted on the front center of the push frame;

[0007] The positioning mechanism includes a support frame, an electric push rod, and a positioning cone. The support frame is installed on both sides of the push frame, the electric push rod is inverted and mounted on the support frame, and the positioning cone is installed at the telescopic end of the electric push rod.

[0008] In one example, the pusher includes a U-shaped frame, a push rod, and a handrail. The walking wheels are rotatably mounted inside the U-shaped frame, the push rod is inclined at the middle of the rear end of the U-shaped frame, and the handrail is mounted on the top of the push rod.

[0009] In one example, the rear end of the U-shaped frame is provided with a fixing plate, on which a lithium battery is installed to supply power to the electric push rod.

[0010] In one example, the walking wheel is connected to the U-shaped frame via a rotating shaft, and a rotary encoder for detecting the rotation angle of the rotating shaft is installed on the U-shaped frame. The rotary encoder is electrically connected to a controller, which is electrically connected to the control port of the electric push rod. A switch button is provided on the handrail.

[0011] In one example, the controller is also electrically connected to a counter for counting the number of times the electric actuator moves and displaying the current number of fixed-point nests.

[0012] In one example, the support frame includes a support plate, a sliding sleeve, and a mounting plate. The support plate is laterally disposed on both sides of the push frame. The sliding sleeve is slidably mounted on the support plate. The mounting plate is disposed on the side of the sliding sleeve. The electric push rod is mounted on the mounting plate.

[0013] In one example, the support plate is square-shaped, and the sliding sleeve is mounted on the support plate by fastening screws.

[0014] The beneficial effects of this utility model are as follows: The transplanter consists of a pusher frame, traveling wheels, and a fixing mechanism. The traveling wheels move in the furrow, completely avoiding contact with the plastic film. The support frame spans across the ridge, and the electric push rod drives the fixing cone to press down vertically, achieving zero-contact fixing marking on the film. In addition, when the rotary encoder detects that the shaft has rotated through a predetermined angle, it triggers the controller to control the extension rod of the electric push rod to extend downward to punch the fixing point, eliminating the need to press the punch every time, greatly simplifying the operation.

[0025] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0026] Please see Figures 1 to 4 This embodiment of a flue-cured tobacco transplanting device includes a pusher frame 1, a traveling wheel 2, and a positioning mechanism 3.

[0027] The push frame 1 includes a U-shaped frame 11, a push rod 12, and a handrail 13. The traveling wheels 2 are rotatably mounted inside the U-shaped frame 11 via a pivot. The push rod 12 is obliquely fixed to the middle of the rear end of the U-shaped frame 11, and the handrail 13 is mounted on the top of the push rod 12. The forward movement of the traveling wheels 2 can be controlled by the handrail 13.

[0028] The marking mechanism 3 includes a support frame 31, an electric push rod 32, and a marking cone 33. The support frame 31 is installed on both sides of the push frame 1. The electric push rod 32 is inverted and mounted on the support frame 31, with its telescopic rod passing through the support frame 31 and pointing vertically downwards. The marking cone 33 is installed at the end of the telescopic rod of the electric push rod 32. By extending and retracting the telescopic rod of the electric push rod 32, the marking cone 33 can move up and down. When it moves to the lowest position, it can punch holes in the mulch film of the ridge to mark the mark. In this embodiment, the marking cone 33 can be a triangular pyramid.

[0029] To facilitate power supply, a fixing plate 14 is installed at the rear end of the U-shaped frame 11, and a lithium battery 37 is installed on the fixing plate 14. The lithium battery 37 is used to supply power to the electric push rod 32.

[0030] For ease of operation, a rotary encoder 34 for detecting the rotation angle of the shaft of the traveling wheel 2 is installed at one end of the U-shaped frame 11. The rotary encoder 34 is electrically connected to the controller, which is electrically connected to the control port of the electric push rod 32. A switch button 35 is provided on the handrail 13. The switch button 35 is used to start the operation. After the rotary encoder 34 detects that the shaft has rotated through a predetermined angle, it transmits a signal to the controller, which then controls the telescopic rod of the electric push rod 32 to extend downwards to achieve fixed-point drilling without requiring the worker to press the drilling button each time.

[0031] To facilitate the synchronous counting of planting holes and subsequent transplanting management, the controller is also electrically connected to a counter 36, which is used to count the number of times the electric push rod 32 moves and display the current number of planting holes at the fixed point. Each time the electric push rod 32 moves, the counter 36 increases the number of planting holes by 2. After the fixed point is completed for each field, the total number of planting holes can be obtained.

[0032] For ease of operation, the support frame 31 includes a support plate 311, a sliding sleeve 312, and a mounting plate 313. The support plate 311 is horizontally fixed on both sides of the push frame 1. The support plate 311 is square in shape. The sliding sleeve 312 is slidably mounted on the support plate 311. The mounting plate 313 is mounted on the side of the sliding sleeve 312. The electric push rod 32 is mounted on the mounting plate 313. After the sliding sleeve 312 is adjusted to the predetermined position, it is fixed on the support plate 311 by fastening screws, thereby realizing the horizontal adjustment of the fixed position.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
